Description

Uplink signal transmission method and device

The application is a divisional application with the name of 'transmission method and device of uplink signals', namely, Chinese patent application No. 201680090607.0 of PCT international patent application PCT/CN2016/106154 with the application date of 2016, 11, month and 16 entering China.

Technical Field

The embodiment of the invention relates to the field of communication, in particular to a method and a device for transmitting uplink signals.

Background

In the current LTE communication system, uplink transmission adopts a single carrier transmission mode, and uplink transmission is mainly performed through Discrete Fourier Transform-Spreading-Frequency Division multiplexing (DFT-S-FDMA) waveforms. The main characteristic of the single carrier transmission scheme is that the ratio (PAPR) between the Peak power and the average power is relatively small. That is, when the terminal performs uplink signal transmission with the network device, the terminal may use a larger power without worrying that the peak power may exceed the maximum transmission power that the terminal can support. In this way, the uplink transmission mode of the single carrier is convenient for increasing the transmission power of the terminal, and the transmission quality and the coverage of the uplink transmission are expanded.

However, when transmitting an uplink signal using the single carrier uplink transmission scheme, physical resources for transmitting uplink data must be contiguous in the frequency domain to satisfy the characteristics of the single carrier transmission scheme. In summary, the physical resource allocation manner of single carrier transmission enables only one type of uplink signal to be transmitted on the entire allocated frequency domain physical resource in one time domain scheduling unit (e.g., timeslot) when transmitting the uplink signal, which limits the flexibility of uplink signal transmission.

Specifically, the time domain scheduling unit may refer to an uplink scheduling period and may refer to a time slot, where the time domain scheduling unit may include 7 OFDM symbols in the case of a normal CP, and the time domain scheduling unit may include 6 OFDM symbols in the case of an extended CP.

The uplink control signal may include different types of uplink signals, for example, an ACK/NACK signal, a CSI feedback signal, and the like.

The physical Resource may be referred to as a Resource Element (RE).

The uplink control signal is transmitted by using a CP-OFDM waveform, which may mean that the uplink control signal is modulated by the CP-OFDM waveform and mapped to a corresponding physical resource.

Optionally, as an embodiment, in the time domain scheduling unit, the physical resource used for transmitting the uplink control signal includes at least one physical resource region, and different physical resource regions are used for transmitting different types of uplink control signals.

In particular, the uplink control signal may include a plurality of different types of uplink control signals.

It should be understood that the above-mentioned physical resource region may include a plurality of resource blocks, which may be consecutive in the frequency domain; the physical resource region may also be a physical resource region on one resource block, that is, one resource block may include at least one physical resource region.

Optionally, each of the at least one physical resource region is composed of at least one frequency domain resource block in a frequency domain.

Optionally, the uplink control signals include uplink control signals of different types, and the physical Resource used for transmitting the uplink control signals may refer to a Resource Block (PRB), where the Resource Block includes at least one physical Resource region, and different physical Resource regions are used for transmitting the uplink control signals of different types.

Specifically, the resource block may be a minimum scheduling unit for uplink signal transmission.

Each of the plurality of physical Resource regions may include a plurality of Resource Elements (REs) contiguous in a frequency domain, and a plurality of OFDM symbols.

Optionally, as an embodiment, the at least one physical resource region includes a first physical resource region, and a first orthogonal frequency division multiplexing OFDM symbol of the first physical resource region in a time domain is a starting OFDM symbol in a time domain scheduling unit.

For example, the first orthogonal frequency division multiplexing OFDM symbol in the time domain of the first physical resource region described above may refer to a first OFDM symbol of a PRB, i.e., a starting OFDM symbol.

Optionally, the at least one physical resource region further comprises a second physical resource region, the second physical resource region being contiguous in time with the first physical resource region.

Optionally, the first physical resource region is used for transmitting ACK/NACK signals, and the second physical resource region is used for transmitting CSI feedback signals.

Optionally, the first physical resource region is also used for transmitting a reference signal, that is, the first physical resource region can simultaneously transmit an ACK/NACK signal and a reference signal, which is used for demodulating the ACK/NACK signal.

It should be understood that the ACK/NACK feedback mode corresponding to the ACK/NACK signal may include an ACK/NACK combining mode and an ACK/NACK multiplexing mode, which is not particularly limited in the present invention.

It should be noted that, when the first physical resource region transmits the uplink control signal, the second physical resource region may also be used for transmitting uplink data; when the first physical resource region transmits an uplink control signal, the second physical resource region may also transmit an uplink control signal, where the uplink control signal transmitted in the first physical resource region may be of a different type from the uplink control signal transmitted in the second physical resource region.

Specifically, fig. 3 is a schematic diagram illustrating a physical resource configuration for transmitting an uplink signal according to an embodiment of the present invention. It should be understood that fig. 3 only illustrates the physical resource of which the first physical resource region includes 2 OFDM symbols, and the embodiment of the present invention does not specifically limit the number of OFDM symbols included in the first physical resource region. As can be seen from fig. 3, the physical resource (e.g., one PRB) in the time domain scheduling unit includes a first physical resource region, and a first OFDM symbol in the first physical resource region (i.e., a first OFDM symbol in the time domain) may be a starting OFDM symbol (i.e., a first OFDM symbol in the time domain) in the time domain scheduling unit.

Optionally, as an embodiment, the at least one physical resource region includes a third physical resource region, and a last OFDM symbol of the third physical resource region in the time domain is a last OFDM symbol in the time domain scheduling unit.

It should be understood that fig. 4 is a schematic diagram illustrating a physical resource configuration for transmitting uplink signals according to another embodiment of the present invention. Fig. 4 only illustrates the physical resource of the third physical resource region that includes 1 OFDM symbol as an example, and the number of OFDM symbols included in the third physical resource region is not particularly limited in the embodiment of the present invention. The physical resources corresponding to the OFDM symbol before the first OFDM symbol (i.e. the starting OFDM symbol) in the third physical resource region may be used for downlink transmission between the network device and the base station. That is, before the first OFDM symbol corresponding to the third physical resource region, switching between downlink transmission and uplink transmission is performed, and uplink transmission may be performed between the network device and the terminal starting from the first OFDM symbol corresponding to the third physical resource region.

It should also be understood that the time-frequency resources before the first OFDM symbol in the third transmission region may include time-frequency resources for uplink transmission, that is, the first physical resources and/or the second physical resources may exist on the time-frequency resources before the first OFDM symbol in the third transmission region, but in the configuration method of the time-frequency resources, the mode of the uplink control signal transmitted by the third physical resources does not belong to the short uplink signal control mode any more.

It is also understood that the second physical resource region and the third physical resource region may be contiguous in time domain, that is, the next OFDM symbol of the last OFDM symbol in the second physical resource region may be the first OFDM symbol in the third physical resource region; there may also be a physical resource region overlapping with the second physical resource region and the third physical resource region, and this is not limited in this embodiment of the present invention.

It should be noted that there may be a physical resource region that is overlapped among the first physical resource region, the second physical resource region, and the third physical resource region, and the first physical resource region, the second physical resource region, and the third physical resource region may also be continuous in a time domain.

Optionally, the uplink control signal includes a plurality of ACK/NACK signals, in the third physical resource region, the physical resources for transmitting the plurality of ACK/NACK signals and the physical resources for transmitting the reference signal do not overlap, and the physical resources included in the resource group for transmitting the plurality of ACK/NACK signals and the physical resources for transmitting the reference signal are arranged in a cross-consecutive manner within the same OFDM symbol.

Specifically, the resource group includes a plurality of physical resources that are contiguous in the frequency domain, for example, a plurality of REs that are contiguous in the frequency domain, within one OFDM symbol.

Alternatively, the physical resources included in the resource group for transmitting the plurality of ACK/NACK signals and the physical resources for transmitting the reference signal may be arranged in a same OFDM symbol in a crossed manner, and the resource group in which the physical resources for transmitting the plurality of ACK/NACK signals are located and the physical resources for transmitting the reference signal may be arranged in a same OFDM symbol in a crossed manner.

Optionally, in the third physical resource transmission region, after the multiple ACK/NACK signals are spread and superimposed by using different orthogonal sequences or pseudo-orthogonal sequences with the same length, the multiple ACK/NACK signals are repeatedly mapped onto resource groups at different positions by the transmission times of the multiple ACK/NACK signals, where the resource groups include physical resources used for transmitting the multiple ACK/NACK signals.

Specifically, the resource groups in different positions may refer to that positions corresponding to the plurality of resource groups are different in the time-domain scheduling unit.

Alternatively, the resource groups of different locations may be contiguous in time and/or frequency domain.

For example, fig. 5 is a schematic diagram illustrating a physical resource configuration for transmitting uplink signals according to another embodiment of the present invention. As can be seen from fig. 5, the locations of the physical resources for transmitting the reference signals and the locations of the resource groups (see the first and second resource groups in fig. 5) for transmitting the ACK/NACK signals are arranged across within the last OFDM symbol. The first ACK/NACK signal and the second ACK/NACK signal occupy consecutive physical resources within the first resource group, while the first ACK/NACK signal and the second ACK/NACK signal occupy consecutive physical resources within the second resource group. That is, the first ACK/NACK signal and the second ACK/NACK signal are transmitted 2 times on the physical resources within the time domain scheduling unit. Wherein the first ACK/NACK signal and the second ACK/NACK signal may be spread-superimposed using different orthogonal sequences or pseudo-orthogonal sequences having the same length.

Optionally, as one embodiment, there is a coincident physical resource region between the second physical resource region and the third physical resource region.

Specifically, the physical resources in the overlapped physical resource region may be configured to the uplink signal transmitted by the second physical resource region, and may also be configured to the uplink signal transmitted by the third physical resource region.

It should be understood that the above-mentioned overlapped physical resource region may refer to a part of the physical resource region in the second physical resource region and a part of the physical resource region in the third physical resource region overlapping, and the above-mentioned overlapped physical resource region may also refer to the second physical resource region including the third physical resource region, and the specific overlapped form in the second physical resource region and the third physical resource region is not limited by the embodiment of the present invention.

Optionally, the uplink signal includes an uplink control signal, a reference signal, and the like.

Optionally, as an embodiment, the uplink control signal includes a first type of uplink control signal and a second type of uplink control signal, and the method further includes: the network equipment configures physical resources used for transmitting the first type of uplink signals for the terminal in the overlapped physical resource area; and the network equipment configures the physical resources used for transmitting the second type of uplink signals for the terminal in the overlapped physical resource area, wherein the priority of the physical resources configured for the first type of uplink signals by the network equipment is higher than the priority of the physical resources configured for the second type of uplink signals by the network equipment.

Specifically, a physical resource region which is overlapped exists between the second physical resource region and the third physical resource region, the second physical resource region is used for transmitting the second type of uplink control signal, the third physical resource region is used for transmitting the first type of uplink control signal, the network device may first configure, for the terminal in the overlapped physical resource region, a physical resource for transmitting the first type of uplink control signal for the terminal, and configure, for the terminal, a physical resource for transmitting the second type of uplink control signal on a physical resource other than the physical resource for transmitting the first type of uplink control signal.

Optionally, the first type of uplink control signal includes an ACK/NACK signal, and the second type of uplink control signal includes a CSI feedback signal.

For example, fig. 6 is a schematic diagram illustrating a physical resource configuration for transmitting uplink signals according to another embodiment of the present invention. As can be seen from the schematic diagram of the uplink transmission resource configuration shown in fig. 6, the first physical resource region includes physical resources corresponding to the first OFDM symbol, the second physical resource region includes physical resources corresponding to the second to fifth OFDM symbols, and the third physical resource region includes physical resources corresponding to the fourth to seventh OFDM symbols, that is, the overlapped physical resource regions between the second physical resource region and the third physical resource region include physical resources corresponding to the fourth OFDM symbol and physical resources corresponding to the fifth OFDM symbol. The first physical resource region is used for transmitting ACK/NACK signals, the second physical resource region is used for transmitting CSI feedback signals, and the third physical resource region is used for transmitting ACK/NACK signals.

It should be noted that any one of the first physical resource region, the second physical resource region and the third physical resource region may also be used for transmitting a reference signal, and the resource allocation diagram shown in fig. 5 is only described by taking the case of transmitting the reference signal in the first physical resource region as an example.

Optionally, as an embodiment, when there is a physical resource region that coincides between the first physical resource region or the second physical resource region and the third physical resource region, that is, the network device configures physical resources used for transmitting the ACK/NACK signal and/or the reference signal in the third physical resource region to the uplink control signal and/or the reference signal transmitted by the first physical resource region or the second physical resource region. At this time, the uplink control signal and/or the reference signal that occupy the physical resource in the third physical resource region for transmission may be punctured (transmitted) by the uplink control signal and/or the reference signal that originally needs to be transmitted in the third physical resource. The problem of resource conflict between uplink control signals and reference signals in different physical resource areas is solved.

220, the network device receives the uplink control signal on the physical resource used for transmitting the uplink control signal, where the uplink control signal is transmitted using a cyclic prefix-orthogonal frequency division multiplexing, CP-OFDM, waveform.

Optionally, as an embodiment, the method further includes: the network equipment determines physical resources used by the terminal for transmitting the reference signals in the time domain scheduling unit, wherein the physical resources used for transmitting the reference signals are configured in any physical resource region of the at least one physical resource region.

Optionally, the third physical resource region is further configured to transmit a reference signal, and the second physical resource region is further configured to transmit a reference signal.

Specifically, the above-described reference signal may be used to demodulate an ACK/NACK signal.

Optionally, the reference signal in the second physical resource region is not transmitted in the overlapped physical resource region.

It should be noted that the position of the physical resource corresponding to the physical resource for transmitting the reference signal may be fixed. That is, the physical resource for transmitting the reference signal in the second physical resource may be fixed, and the physical resource for transmitting the reference signal in the third physical resource may also be fixed. Since the priority of configuring the physical resource for the uplink signal transmitted in the second transmission physical resource region is lower than the priority of configuring the physical resource for the uplink signal transmitted in the third transmission physical resource region in the overlapped physical resource region, in order to avoid that the physical resource originally used for transmitting the reference signal is used for transmitting the uplink control signal in the third physical resource region in the overlapped physical resource region, the network device cannot demodulate the ACK/NACK signal in the first transmission region according to the reference signal (at this time, the physical resource used for transmitting the reference signal may not be configured in the first physical resource region), and when the physical resource is configured for the reference signal transmitted in the second physical resource region, the physical resource used for transmitting the reference signal may not be configured in the overlapped physical resource region.

For example, in the schematic diagram of the uplink transmission resource configuration shown in fig. 6, the reference signal is not transmitted in the physical resource region overlapped between the second physical resource region and the third physical resource region, that is, the physical resource corresponding to the fourth OFDM symbol and the physical resource corresponding to the fifth OFDM symbol.

Optionally, the physical resource for transmitting the reference signal is discrete in a frequency domain or a time domain, or the physical resource for transmitting the reference signal is continuous in the frequency domain and/or the time domain.

Specifically, referring to the arrangement of the physical resources used for transmitting the reference signal in the first physical resource region shown in fig. 6, within one OFDM symbol, the resource group in which the physical resources used for transmitting the reference signal are located is discrete in the frequency domain.

Referring to the arrangement of the physical resources for transmitting the reference signal in the second physical resource region shown in fig. 7, the resource group in which the physical resources for transmitting the reference signal are located includes multiple resource groups, and the resource group in which the physical resources for transmitting the reference signal are located is discrete in the frequency domain (which may mean that the multiple resource groups correspond to different frequencies), where each resource group for transmitting the reference signal occupies two consecutive OFDM symbols.

Referring to the arrangement of the physical resources for transmitting the reference signal in the second physical resource region shown in fig. 8, the resource group in which the physical resources for transmitting the reference signal are located includes a plurality of resource groups, each resource group in the plurality of resource groups occupies two different OFDM symbols, and in one OFDM symbol of the plurality of resource groups, the resource group in which the physical resources for transmitting the reference signal are located is discrete in the frequency domain.

It should be noted that, in the embodiment of the present invention, only the resource group for transmitting the reference signal includes two physical resources is taken as an example for description, the resource group for transmitting the reference signal may further include four physical resources, and the number of the physical resources included in the resource group for transmitting the reference signal is not specifically limited in the embodiment of the present invention.

Optionally, as an embodiment, the uplink control signal includes a plurality of ACK/NACK signals, in the first physical resource region, physical resources for transmitting the plurality of ACK/NACK signals and physical resources for transmitting the reference signal do not overlap, and physical resources included in a resource group for transmitting the plurality of ACK/NACK signals and physical resources for transmitting the reference signal are arranged in a cross-consecutive manner within the same OFDM symbol.

Specifically, the resource group may include a group of consecutive physical resources in the frequency domain, that is, a plurality of resource groups may be included in one OFDM symbol.

The resource group in which at least a part of the physical resources for transmitting the plurality of ACK/NACK signals are located may refer to that all the physical resources for transmitting the plurality of ACK/NACK signals are in one resource group; the resource group in which at least a part of physical resources for transmitting a plurality of ACK/NACK signals are located may also refer to a resource group in which a part of physical resources for transmitting a plurality of ACK/NACK signals are located, and another resource group in which a remaining part of physical resources for transmitting a plurality of ACK/NACK signals are located.

Optionally, when the physical resources for transmitting the plurality of ACK/NACK signals are in a plurality of resource groups, the plurality of resource groups are continuous or discrete in the frequency domain.

For example, fig. 9 is a schematic diagram illustrating a physical resource configuration for transmitting uplink signals according to another embodiment of the present invention. In the resource allocation scheme shown in fig. 9, after the ACK/NACK signal is extended, 8 physical resources (e.g., REs) are required to be occupied for transmitting the ACK/NACK signal, but since only 4 physical resources are included in the resource group between two physical resources for transmitting the reference signal, two resource groups, which are not consecutive in the frequency domain but are consecutive in the frequency domain, may be allocated for the extended ACK/NACK signal, and a total of 8 physical resources.

It should be appreciated that the extended ACK/NACK signals for physical resource transmission in the above-described resource groups

Optionally, the physical resources in the resource group in which the physical resources of the plurality of ACK/NACK signals are located are consecutive in the frequency domain.

Optionally, as an embodiment, the plurality of ACK/NACK signals are respectively spread by using different orthogonal sequences or pseudo-orthogonal sequences with the same length, and then are mapped to the resource group in an overlapping manner.

For example, after a first group of ACK/NACK signals are spread by a first orthogonal sequence and a second group of ACK/NACK signals are spread by a second orthogonal sequence, the first group of ACK/NACK signals and the second group of ACK/NACK signals may have the same length, e.g., the first group of ACK/NACK signals and the second group of ACK/NACK signals may occupy 4 REs, the first group of ACK/NACK signals and the second group of ACK/NACK signals may be mapped on the same resource group, and the resource group may include 4 REs.

Optionally, as an embodiment, the uplink control signal further includes a CSI feedback signal, in the second physical resource transmission region, a physical resource for transmitting the CSI feedback signal and a physical resource for transmitting the reference signal are not overlapped, and physical resources in a resource group for transmitting the reference signal are consecutive in a time domain.

For example, the resource group for transmitting the reference signals includes 2 REs, a first RE and a second RE, where the first RE may be an RE occupying in a first OFDM symbol, the second RE may be an RE occupying in a second OFDM symbol, the first OFDM symbol and the second OFDM symbol are consecutive in a time domain, and the first RE and the second RE correspond to the same subcarrier.

Optionally, as an embodiment, in the first physical resource transmission region, after the multiple ACK/NACK signals are spread and superimposed by using different orthogonal or pseudo-orthogonal sequences with the same length, the multiple ACK/NACK signals are repeatedly mapped onto resource groups at different positions by the transmission times of the multiple ACK/NACK signals.

Specifically, the resource group includes physical resources for transmitting the plurality of ACK/NACK signals.

For example, after a first group of ACK/NACK signals are spread by a first orthogonal sequence and a second group of ACK/NACK signals are spread by a second orthogonal sequence, the first group of ACK/NACK signals and the second group of ACK/NACK signals may have the same length, for example, the first group of ACK/NACK signals and the second group of ACK/NACK signals may occupy 4 REs, the first group of ACK/NACK signals and the second group of ACK/NACK signals may be respectively mapped on different resource groups, and each resource group may include 4 REs.

Optionally, as an embodiment, the multiple ACK/NACK signals respectively correspond to downlink data blocks in different time domain scheduling units, or the multiple ACK/NACK signals correspond to different code words of the same downlink data block.

The method for transmitting uplink signals will be described with reference to fig. 10 by taking subframes as an example. Fig. 9 is a schematic diagram illustrating an uplink signal transmission method according to another embodiment of the present invention. As can be seen from the uplink transmission method shown in fig. 10, the uplink subframe carries ACK/NACK signals of the subframe #0, the subframe #1, and the subframe # k for downlink transmission, where the ACK/NACK signals of the subframe #0 and the subframe #1 are mapped to physical resources in a first resource group of the uplink subframe, and after the physical resources in the first resource group are occupied by the ACK/NACK signals, the ACK/NACK signals of the subframe # k may be mapped to physical resources in a second resource group corresponding to the subframe for uplink transmission.

Optionally, as an embodiment, before the network device receives an uplink control signal on the physical resource used for transmitting the uplink control signal, the method further includes: and the network equipment sends indication information to the terminal, wherein the indication information is used for indicating physical resources used for transmitting the uplink control signals in the time domain scheduling unit.

Specifically, the number of transmissions may refer to the number of repetitions required for the terminal to transmit the uplink control signal.

Optionally, the indicating, by the network device, the number of transmissions required for transmitting the uplink control signal and/or the length of the spreading sequence of the uplink control signal to the terminal includes: and the network equipment sends downlink control information DCI to the terminal, wherein the DCI carries the transmission times required by the transmission of the uplink control signal and/or the length of the extended sequence of the uplink control signal.

Specifically, the network device indicates, to the terminal, the sequence length for sending the uplink control signal and the number of physical resources for the terminal to transmit the uplink control signal, so that the terminal determines the number of transmission times (which may be referred to as the number of repetitions) for transmitting the uplink control signal according to the sequence length for sending the uplink control signal and the number of physical resources for the terminal to transmit the uplink control signal.

For example, the terminal determines that the sequence length for transmitting the uplink control signal is 4, and the network device configures 8 REs for the terminal to transmit the uplink control signal, and the terminal may determine that the number of transmissions for transmitting the uplink control signal is 2.

Optionally, the indicating, by the network device, the number of transmissions required for transmitting the uplink control signal and/or the length of the spreading sequence of the uplink control signal to the terminal includes: and the network equipment sends a high-level signaling to the terminal, wherein the high-level signaling carries the transmission times required for transmitting the first type of uplink signals and/or the length of the extended sequence of the first type of uplink signals.
